An antique gold signet ring

An antique gold signet ring, the oval panel incised with dog's head crest, ring size approximately T

Condition report:
Multiple chips, scuffs, scratches and dings to the mount, commensurate for age and regular use. The edges of the bezel/panel have patchy heavy wear, with losses to the engraved decoration in places. The back of the shank has some deep scuffs/chips to the edges and a filed area where the mount may have been previously acid tested. There are also areas of pitting and an aperture to the back of the panel, which may previously have been glazed. The shank is off-round and establishing an accurate ring size is therefore difficult. The bezel/panel measures approx. 1.85cm length x 1.7cm width. Gold standard is unknown and the mount is not marked. Gross weight approx. 22.6gm.
